Apartments (we stayed in 2 different ones) were new, very well kept and cutely decorated. Located just 5 minute walk from the best BTS Station, Saphan Taksin, which is also the Central stop for the river buses.
Can get to the big shopping malls and pretty much anywhere in the city for under 100 Baht via taxi. Until you get used to the taxi cost, stay away from Tuk Tuks (afterward you can negotiate better.)
Wimonpak was an amazingly responsive and accommodating host! She replied to any of our inquiries within minutes via AirB&B.
Would highly recommend to anyone looking for a clean, cool, spacious and quiet place to stay in Bangkok.
